abstract

mobile robot navigation is one of the basic problems in robotics. in this paper, a new approachis proposed for autonomous mobile robot navigation in an unknown environment. the proposedapproach is based on learning virtual parallel paths that propel the mobile robot toward the trackusing a multi-layer, feed-forward neural network. for training, a human operator navigates themobile robot in some different paths in the environment. both of human operator navigating dataand virtual parallel paths train the neural network. the neural network is able to map thecoordinate of a position to a mobile robot orientation and velocity. after training, the mobile robotcan plan a track between start and target position without the need of any human operator. whenthe environment surrounding the mobile robot is unknown, sensors are used to detect obstaclesand avoid collision. the simulated mobile robot is equipped with a rangefinder sensor. thesimulation shows promising results and high speed for real-time implementation in unknown andpartially dynamic environments.

scour modeling piles of kambuzia industrial city bridge using hec-ras and artificial neural network

today, scouring is one of the important topics in the river and coastal engineering so that the most destruction in the bridges is occurred due to this phenomenon. whereas the bridges are assumed as the most important connecting structures in the communications roads in the country and their importance is doubled while floodwater, thus exact design and maintenance thereof is very crucial. f...

Dynamic Mobile Robot Navigation Using Potential Field Based Immune Network

This paper proposes a potential filed immune network (PFIN) for dynamic navigation of mobile robots in an unknown environment with moving obstacles and fixed/moving targets. The Velocity Obstacle method is utilized to determine imminent obstacle collision of a robot moving in the timevarying environment. The response of the overall immune network is derived by the aid of fuzzy system. Simulatio...

A New Method of Mobile Robot Navigation: Shortest Null Space

In this paper, a new method was proposed for the navigation of a mobile robot in an unknown dynamic environment. The robot could detect only a limited radius of its surrounding with its sensors and it went on the shortest null space (SNS) toward the goal. In the case of no obstacle, SNS was a direct path from the robot to goal; however, in the presence of obstacles, SNS was a space around the r...

Navigation of Nonholonomic Mobile Robot Using Visual Potential Field

In this paper, we develop an algorithm for the navigation of a nonholonomic mobile robot using the visual potential. The robot is equipped with a camera system which dynamically captures the environment. The visual potential is computed from an image sequence and optical flow computed from successive images captured by the camera mounted on the robot. Our robot selects a local pathway using the...
